Double-water-source heat pump system

Abstract

A double-water-source heat pump system belongs to the range of water source heat pump system engineering. Nowadays, the energy conservation effect of a ground source heat pump is quite obvious, and the ground source heat pump has been increasingly approved. For an independent villa yard, a well type heat exchange heat pump is practical; but, generally a large amount of low-temperature cold water replaced out by the well type heat exchange heat pump in winder and a large amount of hot water replaced out by the well type heat exchange heat pump in summer are discharged out of a well and wasted, and if the low-temperature water is stored in winter to be reused in summer and the hot water is stored in summer to be reused in winter, higher energy-saving benefits can be achieved; and therefore development of a water source heat pump system capable of utilizing water in a seasonal manner is particularly necessary. For the requirement above, the double-water-source heat pump system is specially designed. The double-water-source heat pump system comprises heat exchangers, water containing sources, a compressor set, a utilization terminal and a controller. According to the double-water-source heat pump system, by effectively utilizing the beneficial effect that the double water sources supplement each other, the start time of the compressor set is shortened, the work period is optimized, air temperature regulation is conducted for the indoor portion of a building, and the aims of efficient energy conservation and zero emission are achieved.

Description

technical field [0001] The invention belongs to the category of water source heat pump system engineering. Background technique [0002] Nowadays, the energy-saving effect of ground source heat pump is very obvious, and it has been more and more recognized. Buried exchange pipelines are generally used in ground source heat pump assembly projects, but this method takes up too much land and is generally not easy to repair, and it is a one-time project. For single-family villas, the well-type heat exchange heat pump is more practical, but the well-type heat exchange heat pump generally displaces a large amount of low-temperature cold water in winter and replaces a large amount of hot water in summer, which is excluded from the well and wasted. If the low-temperature water is used in winter Store hot water for reuse in summer, and store hot water in summer for reuse in winter, which will bring higher energy-saving benefits; therefore, it is particularly necessary to develop a w...

For single-family villas, the well-type heat exchange heat pump is more practical, but the well-type heat exchange heat pump generally displaces a large amount of low-temperature cold water in winter and replaces a large amount of hot water in summer, which is excluded from the well and wasted. If the low-temperature water is used in winter Store hot water for reuse in summer, and store hot water in summer for reuse in winter, which will bring higher energy-saving benefits; therefore, it is particularly necessary to develop a water-source heat pump system that can be used in different seasons
